Functions ¶

func AppendError ¶

func AppendError(base error, err error) error

Appends one error to another, allowing for operations that return multiple errors to remain compatible within a single-valued context.

func Confirm ¶

func Confirm(prompt string) bool

func Confirmf ¶

func Confirmf(format string, args ...interface{}) bool

Present a confirmation prompt. The function returns true if the user interactively responds with "yes" or "y". Otherwise the function returns false.

func Critical ¶

func Critical(args ...interface{})

func Criticalf ¶

func Criticalf(format string, args ...interface{})

func Debug ¶

func Debug(args ...interface{})

func DebugStack ¶ added in v1.5.50

func DebugStack()

Logs the current stack trace as debug log output.

func Debugf ¶

func Debugf(format string, args ...interface{})

func Debugging ¶

func Debugging() bool

func Dump ¶

func Dump(args ...interface{})

func Dumpf ¶

func Dumpf(format string, args ...interface{})

func Error ¶

func Error(args ...interface{})

func Errorf ¶

func Errorf(format string, args ...interface{})

func Fatal ¶

func Fatal(args ...interface{})

func Fatalf ¶

func Fatalf(format string, args ...interface{})

func Info ¶

func Info(args ...interface{})

func Infof ¶

func Infof(format string, args ...interface{})

func Log ¶

func Log(level Level, args ...interface{})

func Logf ¶

func Logf(level Level, format string, args ...interface{})

func Logger ¶

func Logger() *logging.Logger

func Notice ¶

func Notice(args ...interface{})

func Noticef ¶

func Noticef(format string, args ...interface{})

func Panic ¶

func Panic(args ...interface{})

func Panicf ¶

func Panicf(format string, args ...interface{})

func SetLevel ¶

func SetLevel(level Level, modules ...string)

func SetLevelString ¶

func SetLevelString(level string, modules ...string)

func SetOutput ¶

func SetOutput(w io.Writer)

Set the destination Writer where logs will henceforth be written.

func Warning ¶

func Warning(args ...interface{})

func Warningf ¶

func Warningf(format string, args ...interface{})

Types ¶

type FormattedLogFunc ¶

type FormattedLogFunc func(format string, args ...interface{})

type Level ¶

type Level int

const (
	PANIC Level = iota
	FATAL
	CRITICAL
	ERROR
	WARNING
	NOTICE
	INFO
	DEBUG
)

var LogLevel Level = func() Level {
	if v := os.Getenv(`LOGLEVEL`); v != `` {
		return GetLevel(v)
	} else {
		return INFO
	}
}()

The LOGLEVEL environment variable has final say over the effective log level for all users of this package.

func GetLevel ¶

func GetLevel(level string) Level

func (Level) String ¶

func (self Level) String() string

type LogFunc ¶

type LogFunc func(args ...interface{})

type LogParseFunc ¶

type LogParseFunc func(line string) (Level, string)

type StackItem ¶ added in v1.5.50

type StackItem struct {
	ProgramCounter uintptr
	Filename       string
	Line           int
	Function       string
}

func (StackItem) String ¶ added in v1.5.50

func (self StackItem) String() string

type StackItems ¶ added in v1.5.50

type StackItems []StackItem

func StackTrace ¶ added in v1.5.50

func StackTrace(skip int) StackItems

Retrieves details about the call stack that led to this function call.

type WritableLogger ¶

type WritableLogger struct {
	// contains filtered or unexported fields
}

func NewWritableLogger ¶

func NewWritableLogger(level Level, prefix ...string) *WritableLogger

func (*WritableLogger) SetParserFunc ¶

func (self *WritableLogger) SetParserFunc(fn LogParseFunc) *WritableLogger

func (*WritableLogger) Write ¶

func (self *WritableLogger) Write(p []byte) (int, error)
